PURPOSE:To eliminate binding due to the falling of the bristles of the brush and to maintain the agitation performance for toner and talc by idling only the brush for a specific time prior to copying operation or in a copying stop period. CONSTITUTION:An idling cycle is entered after a time where in there is no impedance to the warm-up of a fixing device 11, e.g. about 130 seconds later, and a main motor 30 is driven to idle a photosensitive body 5 and the brush 13 of the cleaning device 12. Further, when there is no copy signal after a main switch is turned ON, the idle rotation is carried out at intervals of 30 minutes. After copying operation, idle rotation is carried out at intervals of 30 minutes from a cycle-out state. When there is no copying signal after the idle rotation, idle rotation is performed at intervals of 30 minutes. Thus, the bristles of the brush which deform during the stop recover and the binding due to the falling of the bristles of the brush is eliminated only by simple devising by the modification of only software. |
